[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an anti-cracking type environmental protection car film, comprising a car film base body, the upper surface of the car film base body is coated with polyurethane coating, acrylic resin coating, UV absorber coating, silver ion antibacterial coating and silicon dioxide nano coating from bottom to top.

[0006] The upper surface of the car film base body is provided with a plurality of grooves, and the grooves are filled with extension convex bodies, and the extension convex bodies are arranged at the bottom end surface of the polyurethane coating.

[0007] Preferably, the bottom end surface of the car film base body is coated with water-based polyurethane coating.

[0008] Preferably, the UV absorber coating is embedded with a plurality of nano ceramic particles.

[0009] Preferably, the grooves on the car film base body are distributed at equal intervals, and the inner bottom of the groove is a hemispherical structure tapered from bottom to top.

[0010] Preferably, the car film base body is made of PET material.

[0011] The utility model has the advantages of:

[0012] The utility model discloses a polyurethane coating is set up to improve the elasticity and weather resistance of car film, has reduced the possibility that car film leads to the cracking because of stress concentration, also can improve the ability of car film to resist environmental factors, and the ultraviolet resistance of car film is improved with UV absorber coating, can effectively prolong the service life of car film, slows down the aging speed, thereby reduces the cracking risk, and the strength of car film can be significantly improved with the surface coating of silica nano coating, and the wear resistance of car film is enhanced, this helps to keep the car film surface intact, reduces the possibility of forming the crack, this not only improves the aesthetic property of car film, also is favorable to improving the service life of car film.
